The Gunners have fallen well off the pace in the Premier League title race in recent months, with the north London side even dropping out of the top four after Everton’s 1-0 win at Sunderland on Saturday.
Nobody really takes into consideration the relevance of those injuries and the devastation that it has on your team
Arsenal were without form midfielder Aaron Ramsey for three months due to injury and Jack Wilshere is currently sidelined, whilst club-record signing Mesut Ozil is out with a hamstring problem.
“At this stage, he’s suffered his injuries like everyone else at the wrong time,” Allardyce said.
“I think that nobody really takes into consideration the relevance of those injuries and the devastation that it has on your team.
“David Moyes has had the same problem and the huge amount of injuries that he’s sustained means he hasn’t been able to put the same eleven out, particularly defensive wise and of course Robin van Persie.”
Allardyce can sympathise with Wenger after the Hammers struggled without target man Andy Carroll for most of the season.
“We’ve had the same with a long-term injury to Andy Carroll,” Allardyce added.
“All our defenders got injured, particularly our centre halves, and that had a huge effect on us. When that spell comes, it’s very, very difficult to maintain the level of performance and results you’ve achieved before that.
“We just have to keep going and have our squad ready to play whoever we play against.”
